REFLECTING ON THE PROCESS
 Students gained a deeper understanding of all
elements involved in the modeling process
Many students commented on how
the teachings they had previously received had given
them an incorrect conception of what is involved in a
modeling process:
they had a traditional view of a "problem statement"
that requires a fixed, final answer.
But now they understood a modeling process, as an
iterative and improvable activity. 8
